Conversion Factors and Formulas
The conversion factors provided in this section are intended to ease data calculation for systems that do not
conform specifically to the configurations listed in this Site Preparation Guide. Listed below are the
conversion factors used in this document, as well as additional conversion factors which may be helpful in
determining those factors required for site planning.
Conversion Factors
Refrigeration
1 watt = .86 kcal/h
1 watt = 3.412 Btu/h
1 watt = 2.843 x 10
-4
tons
1 ton = 200 Btu/min.
1 ton = 12,000 Btu/h
1 ton = 3,517.2W
Metric Equivalents
1 centimeter = 0.3937 in.
1 meter = 3.28 ft.
1 meter = 1.09 yds
1 in. = 2.54 cm
1 ft. = 0.305m
1 CFM = 1.7m3/h
